Abstract: 1,050,669. Knitting machines. KARL MAYER TEXTIL-MASCHINENFABRIK G.m.b.H. Aug. 4, 1964 [Oct. 22, 1963], No. 30760/64. Heading D1C. To enable the pattern to change for the formation of marginal portions of a fabric produced on a warp machine two pattern mechanisms for operating the levers 1 shogging the thread guide bars of a warp machine are provided. One of the mechanisms, which are in the form of pattern drums 2, 3 or chains, determines the main pattern and the other determines the pattern of the marginal portion. Normally one or the other of the mechanisms is driven through a clutch 5 white the second remains idle but a transitional period occurs during which both are operative. To permit this to occur the links on the drum or chain at that position coincide so that both operate in a similar fashion on the levers 1. This enables the mechanisms to be brought into and out of operation without stopping the machine and without one mechanism interfering with the other.

IPC: G05D1/08
Abstract: 1,052,650. Automatic control of aircraft. NORTH AMERICAN AVIATION Inc. Dec.14, 1964, No. 50866/64. Heading G3R. In a servoloop associated with an automatic pilot for an aircraft, the gain and phase shift of the servo amplifier are controlled automatically to compensate for changes in sensitivity and time constant of the controlled element, using an oscillator whose frequency is outside the normal range to measure the gain and phase shift of the loop, so that these may be maintained constant. As shown (Fig. 5), a basic closed servoloop has an input signal fed in at 17, and comprises amplifiers 26, 27, actuator 29, controlled element 11 and sensor 12 measuring the response of element 11 to derive an output signal which is fed back into amplifier 26 in opposition to the signal at 17. The servoloop is also fed with a test signal from oscillator 15 at a frequency just above the normal frequencies fed through the loop. The output from controlled element 11 at the test frequency is fed through a band pass filter 16 and compared at 31 with the amplitude of the test signal, and at 35 with the phase of the test signal, The amplitude difference detector 31 produces an error signal which causes motor 32 to vary the gain of amplifier 26 by changing a feedback resistor 28, and the phase difference detector output is compared at 36 with a D.C. voltage at 37 representing a predetermined phase change, to alter the phase change of amplifier 27 by motor 38 and gauged input resistor 47 and feedback resistor 48.
